An introduction to Science

Science has given many answers to the questions of life. Science is used to study the way our minds work, the way animals behave and why the world is the way it is. It almost gives us a solution to life; an explanation that we all need deep within our souls. We need science to constantly change and grow along with life.

The word science is derived from the Latin word ‘Scientia’, which translates ‘knowledge’. We can define science as the subject that systematically studies the structure and behavior of the natural and physical phenomena through observation, experimentation and investigation. We use science to help us understand the way in which the universe works and it has made it understandable to mankind. We know what we know because of this subject alone, if we did not have it, we would not know as much as we do and our knowledge would be limited.

There are many different concepts and components of science and it covers many subjects and topics. The scientific method has a numerous phases of science, including observation, hypothesis, inferences and theory. Scientific method is the way in which things are studied when science is involved. When observing something, first data must be collected – known and unknown facts are observed. Based on the observations a hypothesis (an untested statement and states what the study is about and what the scientist will observe) is written. If the hypothesis coincides with the observations then an inference is drawn. Inference in Science refers to coming to a conclusion from the assumption of something that is true. The conclusions can be reached from multiple observations. Theories are ideas or concepts that an individual has drawn, also from observations. Theories can explain how things work. As mentioned above, science has a number of branches, subjects and topics. Science is also part of many other subjects, such as technology, mathematics, engineering and health. There are three main categories of science and under these three many other topics. There are also new fields of science emerging.

The different branches of science cannot be counted on hand and they are all interlinked with each other in some way. The most popular science topics are physics, biology, and chemistry which most individuals are familiar with. Below is a brief definition of these categories and the topics that fall beneath them.

Physics – Physics is the science that deals with the study of matter and the properties of energy and the relationship between them. Classical physics, modern physics and applied physics are all topics that fall underneath this category. Astronomy, cosmology, galactic astronomy and astrophysics are all studies related to space, planets and the universe which also fall underneath physics.

Biology – Biology is the study of life and living organisms. In this field studies life and includes earth sciences, geology and geomorphology. Biology also looks at plants and cells.

Chemistry – Chemistry is a subject that studies the relationship between substances and chemical reactions. Most say that it is a part of physics, but is also well known as an individual topic of science.

The development of science has advanced over the years; scientists are now able to create a human cell in a single test tube. Thanks to science, most diseases can now be cured and further studies of diseases can be researched. Science has helped mankind with so many different areas is life. It has contributed to evolution, technology, medicine and much more. We need science in order to further develop our skills and knowledge.
